OIL-PRESS MAT.

SPECIFICATION forming part of Letters Patent No. 298,920, dated May 20, 1884:.

Application filed January 28, 1884. (N model.)

To all whom it may concern.-

Be it known that I, J OIIN H. VAILE, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful I Improvements in Oil-Press Mats, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to an improvement in presses for extracting oil from seeds or meal, and has for its object, primarily, the simplification and economy of construction of the metal mats which rest upon the divisionplates for the purpose of obtaining the maximum amount or yield of oil from any given quantity of meal or seed, and also the prevention of the reabsorption of the oil into the cake by capillary attraction or otherwise after it has been once expressed.

The novelty consists in the construction and combination of the devices employed, as will be herewith set forth and specifically claimed.

In the accompanying drawings, Figure 1, Sheet 1, is a plan view of my improvedmat. Fig. 2, Sheet 1, is a longitudinal section through the same. Fig. 3, Sheet 2, is a perspective view, showing two boxes or divisionplates with the mats applied thereto, a portion of the upper one being broken away. Fig. 4, Sheet 3, is an enlarged transverse section through one of the boxes and superimposed mat. Fig. 5, Sheet 8, is a longitudinal section of one of the mats, showing a modified form of construction.

A A represent the usual or any suitable division-plates or boxes, having on their upper sides longitudinal or transverse ribs a, and 011 their under sides the longitudinal or trans verse corrugations, to form ribs b,which may be either separate or integral with the boxes or division-plates.

c c are the usual gutters or oil-runs,with outlets d, to permit the expressed oil to pass from one box or division-plate to the one below it, and so on into the oil-receptacle.

D is my improved mat, which may be of cast metal, made malleable, if desired, and of the shape shown. As will be observed, this mat is dished on its upper surface and has transverse or longitudinal slots through it, which form ribs 6, whose shape in cross-see tion is clearly seen in Fig. 3. From this construction it will be seen that these integral ribs give the mat on top a corrugated construction with the slots running in the de pressions. The under sides of these slots are beveled, as seen at f, so as to form enlargements, whereby capillary attraction is prevented. WVhere, as shown in Fig. 3, the ribs to run longitudinally, the slots in the mat which rests on the ribs a should run trans- Versely, and when the ribs a run transversely the slots in the matshould run longitudinally,

so as to afford a firmer and more solid foundation for the pressing-surfaces.

WVhile I have thus described the matas made of cast metal, yet I do not limit myself to this construction, for the ribs 0 might be of wrought metal, or riveted to a rectangular frame, as will be readily understood; or, as seen in Fig. 5, the ribs are in two parts, sand the latter of which may be integral with or united to the frame D, and the former bolted or riveted thereon, as shown.

Another feature of my invention, as seen particularly in Figs. 3 and 4, consists in the combination,with the boX,of the supplemental side walls, E, whose upper ends are bent in and recessed in the under side of the box, so as to form an even and continuous pressing-surface, whether the under side of the box be plain, as at g, or corrugated, as at h, and with the joints r so located as to extend over the meal-enfolding cloth and be beyond its edges.

I am aware that mats corrugated on top have been before devised; but these were merely provided with small perforations for the escape of the oil, which perforations were liable to become choked and required much labor to clean; but with my present construction the choking is obviated to a large extent, and should it occur the mat could be readily and quickly cleansed by passing a knife or bar through the slots from end to end, as will be readily understood.

Having thus fully described my invention, said boxes, of supplemental side walls extend- I claim A ing up and bent in for some distance, and re- 1. A mat for oil-presses, having its upper cessed in the under side of the box, whereby surface corrugated, and with slots extending a smooth and unbroken pressing-surface is 5 through it in the depressions of the corrugaobtained, as and for the purpose specified.

tions, and with the under sides .of said slots enlarged, substantially as and for the purpose JOHN VAILE' specified. Witnesses:
